My card is due for renewel in 2009 and as these cards are not necessary for Polish people living in the UK, why do I need one here.
Because British citizensd in the UK do not need a government issued ID card so the British government can not require EU citizens in the UK to have government issued ID cards. However, Poles do need to register under the Worker Registration Scheme for the first 12 months they want to work in the UK. Of course the form is available in Polish and does not require any visits to any government offices.
I have a 2 year old child (who is registered as Polish), if I do not renew the card will the authourities ask me to leave the country and if so, who will support my partner and child.
I don't think that an EU citizen can actually be deported for failing to have a residency permit. As a general rule an EU citizen can only be deported from an EU state if that state can demonstrate that that citizen is a threat to public order there. However, I for one would not like to test that rule.
